【Abstract】 A thermodynamic equation of state (EOS) for uncharged microemulsion system is established by combining the modified Carnahan Starling equation and Hamaker equation, which describes the attractive interaction between droplets. By using this EOS, phase equilibrium properties of uncharged microemulsion systems are studied. The osmotic pressures of n dodecylpentaoxyethylene ether( C 12 E 5) decane water microemulsion system are calculated and predicted. The liquid liquid equilibria volume fractions of sodium bis(2 ethylhexyl)sulfosuccinate (AOT) octane water and sodium bis(2 ethylhexyl)sulfosuccinate decane water microemulsion systems are calculated. The results are satisfactory.更多还原
